accommodation for big groups
We did quite well with 2 tables of 8, side by side, at Au Petit Extra
(This is maybe not quite in the district you specified but we found that it is really hard to find a decent place for a large group).
There was an even bigger group, other side of the room. It was pretty noisy but a great atmosphere. The food was very good although not awesome. It was Saturday night, so I thought they managed really well.
Also, since most places who do take a large group have room for only one big reservation, so book well ahead!
You can try the Pistou Dejeuner. They are usually open only for breakfast, but if you’re a group, they welcome you in the evening. I think the food is good and what’s great is that the restaurant is all yours. So you can have cocktails on the first floor and then your meal on the mezzanine. www.pistoudejeuner.ca
